This sections is essentially targeting people who would for example start a "not-rt.eu" broadcasting rt content.
Instead the more important question is whether people running tor have to take measures to block access to RT as they may be ISPs.
To use some abductive reasoning, think about how this would apply generally: the law is clearly not written to ban encryption, even though your interpretation would suggest that any encryption amounts to intentional circumvention. If that sounds wrong to you, it's because you've confused the intent/object that the law is concerned with.
Tor operators can see the IP, they can see the DNS, and their operation has the effect of unblocking RT.
I think you missed the point of the abductive argument: you're describing a cat and mouse game, one that is fundamentally unrealistic. The more realistic scenario is that the intent described in the article has nothing to do with encryption, Tor, or anything like that.
We live in a networked world. There's an unbroken physical connection between your hardwired ISP connection and every device connected to Russia (less so with starlink and woman and 5g, but still. )
It's resilient by design, and damaging that, even for good reasons, has secondary consequences.
Going after tor nodes would be overreaching and shortsighted.
